insane: Detect python and perl based tests

match_line_in_files will look for a regex in all files matching a glob.

we use iglob to avoid a complete, recursive scan of all source. iglob is
based on python iterators and will scan as we walk through the directories

pytest are detected by looking for "import pytest" or "from pytest" in any
python file.

perl Test:: is detetected by looking for any t/*.t in the toplevel source
directory.
